BALL-Bassinet.

Specification of Letters latent.

Application filed February 15, 1907. Serial No. 357,442.

Be it known that I, HENRY HE. a citizen of the United States, residingat Philadelphia, in thecounty of Philadelphia and State of Penns lvania, have invented a newvand useful Bal -Bearin of which the following is a specification? My invention relates to ball bearings and has for an especial object the provision of improved means for assembling a ball bearmg of unit construction and for retamlng the bearmg in assembly.

More particularly the invention consists in cutting away one edge of one of the racc rings of such a bearmg sufficiently so that the balls may be inserted in the races by.

suitable means, such as by the application of pressure, varying. the relative sizes of the race rings, etc., preferably without the provision of any filling opening; a retaining ring applied to one of the bearing rings tor preventing accidental displacement of the balls, this ring being shaped so as to prevent the balls fromcontacting with the intersection of the ring and race; and means applied to the bearing rings for holding the retaining ring in place thereon. This construction results in an entirely self contained hearing which maybe handled,'shipped and placed in working position as a unit.

The characteristics and advantages of my invention are hereinafter more fully described in connection with the accompanying drawing which. shows an exemplifying structure embodying the invention.

.The figure is'a partial longitudinal section of a ball bearing to which the invention is applied.

Reference numeral 1 designates the inner bearing ring; 2, the outer bearing ring; 3, races therein; and l, balls running in the races. The edge of the inner bearing ring adjacent to'the ball race is cut away so that the diameter at the point 5 is but slightly greater than the ball contact line of the race. The bearing is assembled by placing the balls in position in the outer race, placing the cut-away portion of the inner .ring against the balls, and applying pressure sufficient to force part 5 of the ring past the balls, which then lie in their proper position in the two races. The processmay be facili tated by increasing the size o t the outer ring means. i i

- 6 is a retaining ring seated on a shoulder 7 in the inner ring, conveniently conical although this is not essential.

8 is'a convex surface of the retaining ring which, if the balls tend to move toward the ring, encounters theballs and prevents themfrom coming in contact with the line of intersection between the retaining ring and the race surface and so prevents possibility of damage to the balls or crumbling of the race, which is liable to occur if the balls come in contact with this line of intersection. g

9 1s. a nut having internal 'threadsengaging an external screw thread formed on the bearing ring, servingto lock the retaining rlng in position; th s nut is only representative of means for holding theretaining ring in position, and instead of the nut a plain rmg shrunk or sprung 1n positlon on the provided withraces, balls in the races, one

of the rings being cut-away at one side to approximately the depth of its race, the ring also being formed with a shoulder adjacent to the race, a retaining ring on said bearing ring having a convexly curved face presented to the balls and a nut engaging a screw thread on the bearing ring and serving to hold the retaining ring in position.

In testimony whereof, I have hereunto aflixed my signature in the presence of two witnesses. v
